Study Notes
Reversible Causes of Cardiac Arrest
- Hypovolemia: Decreased blood volume can lead to inadequate circulation and oxygen delivery to tissues.
- Hypoxia: Insufficient oxygen in the body can result from respiratory failure or inadequate ventilation.
- Hydrogen ions (acidosis): Accumulation of acid in the body can disrupt metabolic processes and lead to cardiac arrest.
- Hypo/hyperkalemia: Abnormal potassium levels can cause arrhythmias; hyperkalemia can lead to peaked T-waves, while hypokalemia may cause U-waves.
- Hypothermia: Low body temperature can slow physiological processes, impair cardiac function, and potentially lead to arrest.
- Tension pneumothorax: Accumulation of air in the pleural space can compress the lung and heart, leading to severe cardiovascular instability.
- Cardiac tamponade: Accumulation of fluid in the pericardial space can restrict heart movement, reducing output and potentially causing arrest.
- Toxins: Various substances (e.g., drugs, chemicals) can depress cardiac function or trigger fatal arrhythmias.
- Thrombosis: Pulmonary embolism (blockage in the lung arteries) or coronary thrombosis (blockage in the coronary arteries) can impede blood flow and oxygen supply to vital organs.
